Use a Linux file system for Mac/PC drive sharing
Authored by: Trusted Content on Feb 24, '04 08:30:10PM
I tried using this to transfer files on my USB key between my Mac and my laptop running Arch Linux. After copying about 1 meg of any file to the key (formatted ext2), my Mac kernel paniced with the following dump:

Sun Feb 22 23:31:59 2004


panic(cpu 0): ext2_cmap: allocation requested inside a block (possible filesystem corruption): qbmask=1023, inode=12, offset=1453568, blkoff=512
